Video files are not eligible for the cloud music library. Are these actually videos, or otherwise incorrectly formatted? Third-party tools may be able to extract audio for you if required.
With any track that has the status Error you can try right-clicking, then Add to Library in order to get Music to have another attempt at matching/uploading that item.
The same might work for tracks that are Waiting, although the faded tracks in your images might represent tracks from another library or device that have yet to finish processing there. On a computer you can also use File > Library > Update Cloud Library in an attempt to resume processing of incomplete updates.
The cloud music library will only accept unique tracks, those marked as duplicates will share properties with other tracks that have already been successfully matched or uploaded. You should eliminate same album duplicates from your library while retaining an original matched/uploaded/purchased copy. See Duplicate songs in iTunes/Music - Apple Community.
The cloud library won't take songs that are too long/short and too high/low a bitrate, and I don't think it particularly likes mono tracks. Your 30 second tracks with long names but no artist/album/track number metadata may also be an issue. Are they stored locally, or waiting to upload from some other computer or device?
Protected AAC files from your active Apple Account should already be included in your cloud library as part of your unhidden purchase history. Any purchases made with a different account will be ineligible. This may include purchases made with the same Apple ID when it was associated with a different email address, if you have ever changed that. Burning to audio CD and ripping back DRM free copies may be a workaround here.
